Polyethylene naphthalate (PEN) film is the product of choice for harsh environment applications, filling the performance gap between polyester films and high-performance polyimide films. Tekra can make a recommendation for Kaladex® PEN film manufactured by Mylar® Specialty Films (formerly DuPont Teijin Films™) or Teonex® PEN film manufactured by Toyobo Film Solutions Limited™ based on your specific performance requirements.
Environmental Film Properties
Kaladex® and Teonex® PEN film have many superior properties, such as:
- Heat resistance
- UV resistance
- Moisture & oxygen barrier
- Good dielectric properties
- High dimensional stability
- Mechanical strength
- Anti-hydrolysis
- Low oligomer extraction
- Chemical resistance
- Excellent handling properties
Tekra’s PEN film options can be used for electrical insulation in high temperature environments such as automotive batteries and fuels cells, solar cells, flat flexible cables, flexible printed circuitry, motors, capacitors, and generators.
These harsh environment films should be considered a specialty product offering. They are manufactured in gauges from 0.6 mil to 10 mil and based on volume, stocking programs can be established to lessen the impact of product availability and lead times.
